An earphone is only as good as its cable. The Silver Premium Cable was designed to realize the full potential of 64 Audio products so that every subtle nuance of the music can be heard from output to ear tip. 200 strands of Silver Plated Copper wire provide an exceptionally transparent audio signal without sound distortion or denigration and minimal micro-phonics. With SPC wiring, Silver Alloy Cores, and Silver Premium Audio Solder, the Premium Silver Cable is our lowest resistance cable available.
